DerelictSDL on ubuntu 7.10

Has anyone tried DerelictSDL on 7.10 recently?

I would have thought this should work, I can't see that I doing anything wrong:

libsdl is 1.2.12. gdc is:
gdc (GCC) 4.1.3 20070831 (prerelease gdc 0.25, using dmd 1.021) (Ubuntu 0.25-4.1.2-16ubuntu1)

root@vm-fruitbat:/mnt/svn/sdltest# dsss build
sdltest.d => sdltest
+ /usr/bin/rebuild -Idsss_imports/ -I. -S./ -I/usr/include/d -S/usr/lib/ -I/usr/include/d -S/usr/lib -I/home/user/d/include/d -S/home/user/d/lib -oqdsss_objs/G -lldl -g sdltest.d -ofsdltest

root@vm-fruitbat:/mnt/svn/sdltest# ./sdltest
Segmentation fault (core dumped)
root@vm-fruitbat:/mnt/svn/sdltest# cat sdltest.d

Based on the backtrace, I don't see that this has anything to do with Derelict. The error is occurring in the SDL library itself. It might be beneficial to whip up a version of the test in C and see if you still get the segfault. If so, you can take it to the SDL mailing list in a form that everyone there will be familiar with.

I wrote a c program which loaded an image and displayed it. That worked ok.

There must be something amis with my config. I don't know what it could be. I'll look into it some more later.

I can confirm this under Kubuntu Feisty. But what's weird is that I can get it to happen (randomly) in different places Shocked

I get either a SIGSEGV or a SIGILL in SDL_WriteLE32(), SDL_CDName(), SDL_SetTimer(), and SDL_CDNumDrives(). I don't like nondeterminism.

[edit]And yes, I tried making a C program that used SDL too, and it works fine.

OK, I don't have anything set up to test on Ubuntu right now. I wiped my Linux drive sometime ago to use for extra storage. If one of you can try it out with DMD and see if you get the same problems, that would be helpful.

Works fine with DMD on Ubuntu 7.10.

Yes that's right. I've tried it too. It doesn't work with gdc for some reason. Thanks for the help. I'll see if I can look at a gdc list or try the latest version.

Was this problem solved? I'm having the same trouble on Ubuntu 7.10.

It works with the DMD compiler from digital mars and not the gnu gdc compiler that's in the ubuntu repositories.

The fix, so far is to install the dmd compiler from the digital mars website. It appears that it's not derelict at this time. I'll let you know as I get a chance to try it out some more.

I've found the problem: if you're using rebuild, remove -q and -rdynamic from export_dynamic in the [link] section of a profile. It seems that this was already posted here...

Thanks. I'll sticky something, or put it on the Wiki, so that it stays in an obvious place.

This makes it a patch destined for the dsss project then?

I doubt Gregor would change the default rebuild configuration, since the config files can be edited by hand. There's really nothing to patch. I assume this problem doesn't crop up very often and could be related to the nature of Derelict.
